The cause of the discoloration could be due to the material that the box is made of. Check to see if the box is also discolored. If the box is made of cardboard, there is a good possibility that the cardboard is affecting the white tee shirts. Also check to see if the humidity in the area where the box is stored is high. A high humidity can result in moisture forming on the inside of the box. I would also suggest that you place the tee shirts into a sealed bag to avoid any other contaminants that may be affecting the color of your shirts.

I assume you are talking about your white clothes turning yellow. If you are asking about colored clothes turning yellow, then I would reccommend that you first check the clothing label to determine the correct washing process. For whites, I always use a capful of Clorox bleach, and use hot water. This tends to work quite well. Again, check your clothing label to ensure that the hot water will not damage your clothes.

If you are talking about white clothes that turned yellow, then you can use oxygen bleaches like Oxi Clean to your laundry when you wash, or you can use 1/2 cup of vinegar to a gallon of water and soak for several hours then rinse well.
Try to avoid what turns white clothes yellow, like deodorant, sweat, dirt and dust, always read the washing instruction label and wash your whites after each wear.

The person`s white clothes turn yellow after storing them for a long time, if the person bleach them. Borax should be used, which keeps them white, stainless and also the fabric of clothes remain in well condition.It is not a very expensive product, Just mix a little amount of it with washing powder, when wash clothes.

Many times , white clothes turn yellowish white because of being washed in hard water. If water is not hard, then the cause of white clothes turning yellowish white could be excess use of bleach over the clothes. RIT color extractor can be used to turn the yellowish white clothes back to their original color i.e. white again. Tim Doubtson.
